CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 433,305, dated July 29, 1890.

Application filed December 26, 1889. Serial No. 335,010. (No model.)

To all whom it may concern:

Be it known that I, \VARREN PORTLOOK, of San Diego, in the county of San Diego and State of California, have invented a new and useful Improvement in Car- Couplings, of

which the following is a specification.

My invention has for its object to provide a car-coupling of simple construction which will operate to automatically couple cars in [o a simple and effective manner.

My invention consists in certain novel features of construction and peculiar combination of parts, all of which will be hereinafter fully described in the annexed specification,

r 5 and particularly pointed out in the claims, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of the meeting ends of two cars, with my improved coup- 2o ling-heads applied. Fig. 2 is a top plan view,

partlyin section, of the same coupled. Fig.

3 is a side view of the same coupled, but applied to passenger-car platforms and Fig. 4

is a detail View hereinafter specifically re- 2 5 ferred to.

In the accompanying drawings, A A indicate the ends of box or freight cars, for which my improved coupling is more especially adapted, it being understood, however, that the same may be readily applied to passengercars without changing the construction thereof. B B denote the draw-bars, one of which Bis formed with a vertical head I), having a recessed or forked end, forming horizontal 3 5 arms b h disposed in the same vertical alignment, the outer ends of which are formed with the usual pin-receiving holes 1) 12*, adapted to receive the coupling-pin C.

In adjusting the draw'bar B in position I 40 arrange same so it will have a slight lateral movement in its support B for a purpose presently explained. The draw-bar B has its head 5 bifurcated, and is formed with arms b b in a manner similar to the head I) of the 4$ bar B; but it is disposed horizontally, so as to engage the head I) at right angles thereto. In horizontal slots b b, formed in the arms b l) of the head 6 I pivot the swinging coupling-links D D, one of which D is of less length than the link D. To provide said links for automatic operation to couple the heads together, I pivot them in a novel manner and arrange their projecting ends (Z d to engage each other, so as to serve as a means for returning the links to a position for coupling after they have been engaged by the pin C. To this end I pivot the said links in a manner most clearly illustrated in Fig. 4 of the drawings, from which it will be observed I pivot the link D at d and the link D at (1 said pivot (Z being at a point to the rear of and slightly in advance of the pivot (P. The rear end (1 of the link D is formed slightly cam-shaped and normally engages the end (1 of the link D at a point between their pivots. By this construction it will be observed that when the cars come together the vertically-disposed pin C will enter between the bifurcated ends of the drawhead I)", the arms Z) Z) of the head B being disposed over and under the said horizontal head B in a manner clearly shown in Fig. 3 of the drawings.

As the pin 0 engages the link D, it will swing same to a posit-ion shown in dotted lines, Fig. 4, and owing to the lateral movement of the head B will pass by said link and engage the link D and swing same to a position shown at dotted lines 3, Fig. 4. Now it will be seen that after the pin C passes the link D and engages the link D the rear end of the said link D will engage the link D in advance of its pivot, and the end d, being also slightly cam-shaped, as shown, will force said link back over the slot and thereby lock the pin in and thereby coupling the cars together. Now, when the draw-bar B is pulled forward the pin C will engage the rear edge of the link D and cause it to move forward against a stop portion b of the head 19 such movement causing the cam-like end d of said link to engage the end (1 to the rear of its pivot, thereby swinging the said link back into normal position.

In Fig. 3 I have shown the draw-bar B B as applied to the platforms of passenger-cars. It will be observed that I extend the horizon tal draw-bar B beyond the platform while the bar B hasonly its extreme end beyond its platform, thereby enabling said platforms to come close together.

It Will be understood that in the practical application of my coupler I will construct the draw-heads B and B with both the vertical and horizontal bifurcated heads, so the cars may be readilycoupled from either end in a manner clearly understood by those familiar with couplings of this class.

From the foregoing description, taken in connection with the drawings, the advantages of my improved coupler will readily appear.

It Will be seen that the same is exceedingly simplein construction and operation, and may be readily applied to carsnow in use without changing the construction thereof.

Having thusdescribed my-invention, What I claiin and desire; to secure by Letters Pat-i ent, is

1. An improved camcoupler, consisting of a vertically disposed draw-head B, horizontally bifurcated, a coupling-pin 0, held in theend of said bifureatedhead, a horizontally-dis posed head B,vertically bifurcated, swinging links D D ,-disposed in the end of said bifurcated headB, the link D provided with a projectiond engaging the link D-inadvance of its pivot, said pin O-adaptedvto enter the slotted endof the bar B, to engage and pass.- the link D-in coupling andto, engage the link 4 D, whereby. its projecting portion d will engage the link D and swing it over thebifurcated end, of the head B, substantially as and.

for thepurpose described.

2. The combination, with ;tl1e.vertically -bifurcated draw-head B, provided with a coupling-pin C in its outer end, of the horizontallybifurcated draw-head 13, provided with hori zontally-disposed swinging links D D pivoted at one end to one side of the said draw-head, the link D provided with a cam-like projectrng end d, the link D- having a similar proj ection d, said projectiond engaging thelink the link D and force it baek to its normalpodescribed. 3. The combination, with the vertically slotteddraw-headB, providedwith a cou plin g- B, the links D Di, pivoted in said headB to.

, sition, substantially as and, for the ,p1 rpose,

I pin 0, of ,the horizontally-slotteddraw-head swing in a horizontal plane, provided .With abutting extensionsd d,'the linksD pivoted in advance of thelink D, a shoulder. or '.ab,11t-..

inent on said head B for limiting theforward stantially as, and for thepui'pose described. i RRE ORT Q KQ.
